At its lower end, the vibratory frame '24 has a lateral arm 3'!adjustably connected, by an eccentric pivot-stud 38, to one end of apitman 39. strap 40 embracing an actuating element in the form of anadjustable eccentric 41 carried by a needle-vibrating shaft 42 disposedbelow and extending horizontally crosswise of the shaft l4. Theeccentric 4| may be of any usual or suitable construction, beingconstructed and adjustable in the present case substantially as Theopposite end of the pitman 39 has a 1 65 forming between them a guideway66.

to W. Myers, No. 2,128,031, Aug. 23, 1938. By means of the describedmechanism, the pendulous yoke 45, 46, 41 is actuated to swing back andforth about the axis of rotation of the main-shaft l4; the amplitude ofswinging movement of the yoke being selectively predetermined by adjustment of the eccentricity of the feed-advance eccentric '64.

' The upper member 45 of the pridulous yoke is provided at one end withdepending furcations Slidably disposed in the guideway 66 and confinedby the furcations 65 for movement with the yoke member 45 is a flattenedextension 31' of the needle bar frame arm 31. Consequently, theneedle-bar frame 24 is constrained by the pendulous more fully disclosedin the U. S. patent to C. F. 1

Gray, No. 1,020,089, Mar. 12, 1912.

' motions with the pinion-gear-49, the swinging frame 24 is vibratedabout the fulcrum-stud 39 in substantially the vertical planecontainingthe axis of rotation of the main-shaft l4. In the presentmachine, the ratio of the gears 4 3 and 49 is such that the main-shaftl4 rotates twice for each rotation of the cross-shaft 42.

Th upper member 45 of the yoke, in which the cross-shaft 42 isjournaled, is preferably-integrally provided with horizontally spacedarms 50 and 5| extending upwardly from said yokemember 45. The yoke-arm50 is horizontally apertured to receive a wear-sleeve 52 pivotallymounted upon a reduced end of a bearing-bushing 53 in which themain-shaft I4 is journaled; The other arm 5| of the yoke is likewisehorizontally apertured to receivea wear-sleeve 54 pivot-. ally embracingthe main-shaft M; the yok being therefore pendulously journaledcoaxially of the main-shaft [4. The yoke is held against movementendwise of the shaft I4 by the bearings [0 below the bracket-armstandard I l. The lower member 41 of the yoke is disposed below thebed-plate Hi to extend lengthwise thereof; said member 41 being providedbetween its ends with 9. lug 51 pivotally connected to one end of a 58extending crosswise of the bed-plate ID. The

other end of the link '58 is pivotally connected to a crank-arm'59suitably secured upon a feedadvance rock-shaft 60. The rock-shaft 60' isjournaled in suitable lugs depending from the bed-plate IE1 at therearwardside thereof; said rock-shaft 60 carryinglanother crank-arm 5ipivotally connected tov the lower end of a pitman 62 disposed generallyVertically in the bracketarm standard I l. The upper end of the pitman52 has a strap 63 embracing an adjustable feed; advance eccentric 64carried by the main-shaft 14. The eccentric 64 may be constructed in anyusual or suitable manner, the present eccentric corresponding generallyin structure to that more fully illustrated and described in the U; S:patent The crossshaft- 42 isrotatably journaled in bearing-bosses yoketo vibrate about the fulcrum-pin 21 transversely of the length of thebracket-arm l2, i. e., to vibrate transversely of the vibratorymovements imparted to said frame by the pitman 39. 1 In the presentmachine, the vibratory movemerits iii transverse'direetiens of the frame24 are timed with respect to' the enawise reeipreeatiohs of the needleto effect the production of zigzag stitches; the needle being vibratedin the line of feed while the needle is in the work to assist in feedingthe work. and the needle being vibrated crosswise or the line of feedduring the return movement of the needle while out of the work. It is'tobeundersto'od; however, that the presentinvention in its broader aspectsis not limited to any specific timing of the needle actuating mechanism.

The end face of'the arm 45 of the pendulous yoke, above the furcations55 of said yoke. is grooved vertically to provide a recessed seat 6! fora guideebracket 63 secured to the arm 45 by screws,- as 69; Theguidegbracket 68 base verti cally disposed guideway 'Hlf-or aguide-block ll pivotally sleeved upon the stud-pin [9 extending fro mthe needle-bar 2|; The apertured lower end of the needle-barreciprocating link [8 embraces the sleeve H' of the guide-block ll, saidsleeve llv accommodating endv'vis'e movements of the stud pin I9withinthe, sleeve during lateral movements ofthe needle-bar 2!. Theguide- -blook 'l'l is confined within the guideway 'lli'by' gibs ,12'suitably secured upon the euiideway 10.

Inasmuch as the needleb'ar.frame Z4 is splin'ed to the yoke-arm 45 forpositive swinging movement with the pendulous yoke which has a p'ivotalaxis coincident with that of the frame 24, the needle bar' 2| and theguideway 70 are con-- stantly maintained inparane1ism. The describedguiding means minimizes side thrust upon the needle-bar 2! by the linkI8 throughout the i i= bratory movements of saidrieedle b'ar.

Complemental to the needle 26 in the formation of lock-stitches is aloop-taker 13 disposed below the bed-plate IO and'o'f the rotary hooktype having itsaxis of rotation extending hori-' zo-ntally crosswise ofthe bed-plate I0, whereby the loop-taker rotates in a; vertical planesubstantially parallel to the plane of vibration of the needle-bar frame24 about the fulcrurn-stud 3'3; Jourh'aled in the loop-taker 13 istheusual,

reread-earn r 14 about which the needle-thread loops areca'st bytheloop-taker. I The loop-taker 13 is carried by the rearward end ofahorizontally dispos'edlodp-taker shaft 15 rotatably jour- Attached tothe yoke-boss.

of the yoke-arm 45.

theopposite end is suitablypivoted to an arm 104 I 11- is the shank of astop-arm 89 which engages and restrains the thread-carrier 1'4 fromrotation with the loop-taker I3. Being carried by the arm 41 of thependulous'yoke keyed to the needle-bar frame 24, the loop-taker 13follows the needle 26 in its lateral movements about the fulcrum-pin2'1. As the loop-taker 13 also has the capacity, as usual, toaccommodatelimited lateral movements of the needle 29 about thefulcrum-stud 39, the loop-taker is adapted to cooperate. with the needle26 in the diiTerentpositions of the needle incidental to the vibrationthereof in transverse directions.

. carries a driven belt-pulley 85 andis rotatably journaled;adjacent'said pulley, in aball-b'earing 86 provided in the. pendulousyoke at thejunction of the yoke-arms 46 and 41. The. driven pulley 85 isconnected by a clip-belt 81 to a driving pulley 88 carried by the mainshaft [4, The. pulleys '85 and B8 are proportioned so? that the loop-[-.

taker actuating shaft 83 rotates twice for each I rotation of themain-shaft I4. As the loop-taker of a bell'crank lever I94, I05. Theothergarm-of thebellcrank'lever l05is connected by a link M6 to *adepending arm I01 of a rock-shaft 'lfl8'dis1- posedsubstantiallyparallel to the main-shaft I4.

The rock-shaft I98 is journaled,inbearing-lugs l 09 extending'rearwardly from, the bracket arm l2; said rock-shaft I88 havinganothercrank-arm ;I I0 pivotally connectedtooneend of a .-pitman I Il-provided with astrap embracing an eccentric I12 carried by themain-shaft ,I4.

,The bellcrank lever [05 is fulcrumed-upon a supporting-block ,1 l3secured upon a vertically disposed and spring-depressed presser-bar vH4.

The presser-bar H4 4 is journaled: for endwise movement in suitablebearings provided in the bracket-arm head 13 Theelower end; ofthepresser-bar H4 carries a presser-foot H5 yieldingly opposed to thework-support and having a feeding-foot clearance slot H6. The presser-foogt H5 and feeding foot sc r reciprocallyraised and lowered in theusual manner by the described actuating mechanism to alternately engagethe work When the feeding-foot 98 descends, the work clamped betweensaid fe eding-foot,and

the feed-plate 89 while the needle 28 is inlthe work. As the severalfeeding elements are all constrained to movefwiththe pendulousyoke, theyact in unison to advance the work engaged thereby. Thefpresser-foot I 15functions to clamp the work against the stationary work-support duringthe-return movement of the needle, feedplateand feeding-foot.

actuating shaft 83 is carried y the pendulous I yoke which swings abouttheaxis of rotation of the main-shaft E4, the pulleys 85-v and 88 aremaintained a fixed distance apart throughout the" swinging movements ofthe yoke.

The needle 26 is assisted to advance the work by a feeding mechanism ofthe clamp-feed type which is commercially well'known. as a unison feedmechanism. Alower two-motion. and serrated feed-plate 89 operatesbackand forth through a suitably slotted plate 99 provided upon thework-support or bed-plate 1;. the work-engaging. teeth of saidfeed-plate89 being constantly maintained'substantially at the level of the upperface of the plate 90. The feed-plate 89' has a needle-slot! elongatedlengthwise'of the .bed-pl'ate l9, said feed-plate being secured upon afeed-bar 92 pivotally connected in any usual or suitable manner to afeed-rocker 93 at one end of the feed-advance rock-shaft 69. The

95 carried by an eccentric -stud 98 adjustably secured in a lug 9"!depending from the bed-plate l9.

Opposed to the feed-plate 89is a feeding-foot 98, having a serratedwork-engaging face and provided with a needle-slot 99 parallel to theneedle-slot 9| of the feed-dog 89. The feedin foot 98 has the shankthereof suitably secured to the lower end of a vertically disposedfeed-bar The feed-bar I9!) is disposed adjacent and substantiallyparallel to'the needle-bar 2|, said feed-bar being journaled for'endwise reciprocation in a vertically apertured boss I0! formed atoneend of a vertically flattened arm [92 comprising an extension of therearward furcation 65 The feed-bar, I08 is therefore constrained toswing with the pendulous yoke about the rotation axis of the main-shafti4 and with the needle in the swinging movements of the latter about thefulcrum-pin 21. I

The upper end of the feed-bar I89 is pivotally connected to one. end ofa short link 103 of which,v

' ,In the operation of the machine, the feed ad Vance rock-shafttransmits (so-directional movements in. unison to the feed-plate 89 andto the pendulous yoke 45, 46, 41. As the needle-bar frame 24 isconstrained to vibrate withithe yokemember and the upperfeed-bafr I 99is carriedby said yoke-member," the several work-advancing elementscomprisingthe needle 26, the'feed-plate B9 and-the. feeding-foot 98opposed to said feed,-

plate are'actuated in unison to-advance the work. Adjustment of thefeed-advance eccentric 64 carried bythe main-shaft I4 determines the Iamplitude of movement of the several feeding "elements, a'nd as theeccentric 64'is carried by the feed-bar 92'has a fork 94 embracing apivot-block shaft l4 .from which the needle-bar 2| derives itsendwise-reciprocation it will be understood that the work is advancedonce for each complete reciprocation of the needle.

'. In the present machine, the endwise reciprocationsof the needle 26are time'dso that said needle is in the work during the rearward oreffective work-advancing movements of the feedplate 89 and thefeeding-foot 98. -The needle'26' is additionally vibrated crosswise ofthe line of feed, while the needle-is outof the work, from theneedlevibrating eccentric 4! to, eiTect the production of zigzagstitches. Being carried by the pendulous yoke, the eccentric 4| and itsconnectionswith the needle-bar frame 24 swing with the yoke and theneedle-bar frame, whereby an effective relationship of the parts isconstantly maintained. vDuring the swinging movements of the pendu- 1ous yoke 45, 46, 41, the needle-vibrating eccentric 4| is slightlyaccelerated and retarded in its -rotation by reason of the rollingaction of the driven spiral gear 48 about its driving gear 49. Acorresponding acceleration and retardation of the-loop-taker 13 occursatthe same time by reason of the belt-connection between the mainshaft14 and the loop-taker actuating shaft 83. .As the endwise movements ofthe needle-bar 2| reciprocating said needle, means for laterally Vi--brat-mg said needre in directions itrans'versetto one another about afixed lpi'vo't poifit substam nary coincident with the axis ofrotatibilof said shaft, 3, loop-taker eor memental to s needle in theformation of stitches, means for etu "ng Solid loop-taker, and means forpend swinging said loop-taker bodily 'aboilt the p "axisof said needlein one directionor vibration ofjand with said needle.
